Can someone please help me? A 485 kg sphere sits at 14.0 km due north of an 852 kg sphere. What is the force of gravity on the first sphere due to the second sphere? Compare this to the force of gravity on the second sphere due to the first sphere.

A250-n box is at rest on a frictionless horizotal floor. then a person shoves the box with a non-zero force of magnitude p. which statement best describes the relationship betweeen p and the motion of the box after it was shoved? -the box will not move when p< 250n but otherwise will accelerate at a constant rate that is directly proportional to p - the box will begin moving at a speed that is directly proportional to p, then will gradually slow to a halt -the box will move with constant velocity at a speed that is directly proportional to p -box will accelerate across the floor at a constant rate that is directly proportional to p
